Upon completion, it will greatly alleviate the water shortage in urban construction and industrial development along the Weihe River. The project covers an area of 14,500 square kilometers and a beneficiary population of 14.11 million.

It has inspired grandiose ambition, and the workers have made a silent vow to the project. For more than 2,000 days and nights, in the Qinling Mountains Water Conveyance Tunnel, they work on a 12-hour shift. With the rapid pace of technological innovation, the tunnel-boring machines are more reliable with radar sensors stopping them from crashing. They roll 24 hours a day. The tunnel borer can only advance 3 to 4 meters a day, but every meter is made at the price of sweat and toil. In the tunnel with high temperature and humidity, it is just normal for the workers to put up with dizziness, vomiting and even fainting. What scares them most is the geological disasters and nobody knows when they will happen.
